Republican presidential candidate Mitt Romney today announced the support of businessman and reality television star Donald Trump.

“I am humbled by the endorsements I have received from Republicans across the political spectrum. Donald Trump’s endorsement of me today sends a strong signal that he believes we have the best chance to make President Obama a one-term president,” Romney said in a news release “We share both a background in the private sector and a belief that Washington needs to get out of the way of small business. His support is a sign that business leaders are fed up with Washington and want someone with actual experience creating jobs and working in the real economy in the White House.”

Is that what it’s a sign of? I’m not so sure. Trump is more showman than businessman, and poll results released last month by the Pew Research Center and Washington Post showed that almost three times as many voters would view a Trump endorsement negatively (28 percent) as positively (8 percent) with 63 percent not caring at all.

For example, Trump said on the Fox News Channel last August – as Republicans warred with President Obama about raising the debt ceiling – that “Romney has been missing in action. He hasn’t done a damn.” Trump the same day noted he “wasn’t in love” with Romney’s tenure as Massachusetts’ governor: “He wasn’t popular; he was a one-term governor; he didn’t have high approval ratings.”

And way back in April, Trump had told CNN that Romney “is a basically small business guy. He was a hedge fund guy, a fund guy, he walked away with some money from a very good company that he didn’t create; he worked there. He would buy companies; he’d close companies; he’d get rid of jobs.”
